Composition retained from the cited study below. Calculation aid for research planning. C14-PEG2000 is treated using an approximate average molecular weight; confirm the exact supplier or batch value before use. The result covers lipid component weights only and does not include RNA, buffer, solvent, process loss or N/P ratio.

Reported preparation contextAqueous sup-tRNA in 10 mM citrate buffer (pH 4.0) was mixed with the ethanol lipid phase at a 3:1 aqueous-to-organic volume ratio using a T-junction device. The LNPs were then dialyzed against PBS overnight at 4 °C and concentrated using 100 kDa MWCO filters.
